Abstract: PURPOSE: A reed solomon decoder having three stages is provided to operate in the pipeline mode and to reduce the initial delay time and the power by using the variable processing. CONSTITUTION: A reed solomon decoder has a three stages pipeline structure. A first stage(210) comprises a syndrome polynomial calculator(211) for calculating a syndrome polynomial based on the input data, and an erasure position polynomial calculator(212) for computing the eraser position polynomial by receiving the erasure flag signal. At the second stage(220), an errata position polynomial calculator(221) receives a syndrome polynomial and an erasure position polynomial and computes the errata position polynomial. A third stage(230) comprises an errata value calculator(231) for computing the errata value by using the errata position polynomial and the syndrome polynomial, and an output requester used to verify the result. Thus a reed solomon decoder reduces the stages from the conventional four stages to three stages and decreases the initial delay time.
